The spokesman says the pilot lost consciousness "somewhere over Oregon." He later regained consciousness and left the cockpit. McElroy says a doctor on board tended to him in the cabin. The pilot has been taken to a hospital but there was no immediate word on his condition.

The Boeing 737-700 with 116 passengers and five crew members left Los Angeles about 6:30 p.m. PST and touched down in Portland at about 9 p.m.

McElroy says the pilot has been flying for Alaska for 28 years and was current on his six-month medical evaluation.
